This app is fantastic
This app works exactly how you want it to. There are shortcuts to easily take a snapshot/screenshot/screen capture of your desktop. Then the application quickly opens up with the ability to add arrows, boxes, text, emoji and more. The best part for me was being able to drag my edited photo where I wanted it. Oh, and it gives you the option to share a link of your photo to various destinations - and it linked to my dropbox account in a few short clicks. Very well thought out and executed!
